guns, it's its people. that's fine, but this character, 22 years old, seemed perfectly normal to everybody who knew him. family, friends, school colleagues, whatever. everyone who had ever known this guy said mr. normal. not a clue that he would ever do this, and yet he goes into a shopping mall and begins shooting people in what was a very similar in, my view, kind of thing that we saw in aurora. maybe a copy cat, cry for attention, whatever it is. you can't legislate for that. all you can do is try to remove that guy's ability to find an ar-15. or steal one, as he did. >> and you're not going to remove it, though. >> why not? >> if he doesn't get the ar-15, he'll go get a handgun. if he doesn't do that, he'll go get explosives. if he doesn't get that, he'll go get poison. >> but don't you have to try when you're running a country with so many guns to try to make it harder? >> i think i probably with bill bratten seized more guns in new york city than any mayor in history.
